我需要使用 PUT 發(fā)送 PDF 附件，就像您在 POSTMAN POSTMAN Examples中附加文檔一樣。我正在使用的服務僅接受請求正文中的 PDF 文件。這是我的代碼：// create new fileFileSystemResource file = new FileSystemResource(new File("/Users/name/Documents/test.pdf"));MultiValueMap<String, Object> body = new LinkedMultiValueMap<>();body.add("file", file);// adding basic authHttpHeaders headers = createHeaders(username, password);// required custom headerheaders.set("X-Async-Scope", timelineEntryId);HttpEntity<MultiValueMap<String, Object>> requestEntity = new HttpEntity<>(body, headers);RestTemplate restTemplate = new RestTemplate();ResponseEntity<String> response = restTemplate.exchange(baseUrl, HttpMethod.PUT, requestEntity, String.class);問題是響應帶有狀態(tài)代碼415 Unsupported Media Type，我不知道為什么。我的 HttpEntity 正文格式錯誤嗎？

HttpHeaders headers = createHeaders(username, password);
headers.setContentType(MediaType.APPLICATION_PDF);
headers.set("X-Async-Scope", timelineEntryId);
InputStream inputStream = new FileSystemResource(new File(file.getPath())).getInputStream();
byte[] binaryData = IOUtils.toByteArray(inputStream);
HttpEntity<byte[]> requestEntity = new HttpEntity<>(binaryData, headers);
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<String> response = restTemplate.exchange(baseUrl, HttpMethod.PUT, requestEntity, String.class);

也許，您需要設置標題內(nèi)容類型？
headers.set("Content-Type", "application/pdf")如果沒有幫助，您還應該設置標頭 Content-Disposition：
headers.set("Content-Disposition", "attachment; filename="+fileName)

你可以試穿
String headerKey = "Content-Disposition";
String headerValue = "attachment; filename=category_list" + ".xlsx";
response.setHeader(headerKey, headerValue);
categoryServiceImpl.exportToExcelFile(response);
